CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of and claims the benefit of and priority to U.S. application Ser. No. 15/936,863, entitled “BOT GROUP MESSAGING METHOD” filed Mar. 27, 2018, and U.S. Provisional Patent Application No. 62/477,043, filed on Mar. 27, 2017, by the same title, both of which are incorporated by reference in their entirety.

BACKGROUND

With the worldwide proliferation of the internet, providing goods and services to users and consumers has become more commonplace and automated. One way that automatically providing increased numbers of goods and services is through bots. An internet Bot, also known as web robot, WWW robot or simply bot, is a software application that runs automated tasks (scripts) over the internet. Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone. The largest current use of bots is in web spidering or web crawling, in which an automated script fetches, analyzes and files information from web servers at many times the speed of a human. More than half of all web traffic is made up of bots.

Some bots communicate with other users of internet-based services, via Instant Messaging (IM), Internet Relay Chat (IRC), or another web interface such as Facebook Bots and Twitterbots. These chatterbots may allow people to ask questions in plain English and then formulate a proper response. These bots can often handle many tasks, including reporting weather, zip-code information, sports scores, converting currency or other units, etc. Others are used for entertainment, such as SmarterChild on AOL Instant Messenger and MSN Messenger. An additional role of IRC bots may be to lurk in the background of a conversation channel, commenting on certain phrases uttered by the participants (based on pattern matching). This is sometimes used as a help service for new users, or for censorship of profanity.

General-purpose bots, such as Amazon's Alexa, Microsoft's Cortana, Google's Assistant, and Apple's Siri, are digital personal assistants able to provide a wide range of consumer-oriented voice-activated services, including turning lights on/off, controlling appliances, playing requested music from services such as Pandora or Spotify, providing requested information, or ordering products or services.

OVERVIEW

With increasing interest in bot-based platforms and internet ease of use, it is desirable to create a new generation of messaging services that allow groups of users to interact with both user-oriented bots as well as group-oriented bots. The present disclosure provides advantages for bot environments. Methods, apparatuses, and computing systems are provided for bot messaging.

In an implementation, a method may include one or more of receiving, by a group messaging service coupled to the internet and a group, a message from a user node of the group. The message includes an address and an identification of the group and the user node. The method further includes determining that the group includes a bot, which includes a software application for performing one or more tasks over the internet. The method also includes identifying that the message address corresponds to the bot and sending, by the group messaging service, the message to the bot.

In another implementation, a non-transitory computer readable storage medium is provided. The non-transitory computer readable storage medium is configured to store computer instructions that when executed cause a processor to perform one or more of receiving, by a group messaging service coupled to the internet and a group and comprising the processor, a message from a user node of the group, determining that the group includes a bot, which includes a software application for performing one or more tasks over the internet, identifying that the message address corresponds to the bot, and sending, by the group messaging service, the message to the bot. The message includes an address and an identification of the group and the user node.

In yet another implementation, a computing system is provided. The computing system includes one or more of a storage system including program instructions and a processing system, operably coupled to the storage system. Program instructions when executed by the processing system are directed to receive, by a group messaging service coupled to the internet and a group, a message from a user node of the group. The message includes an address and an identification of the group and the user node. The program instructions when executed by the processing system are further directed to determine that the group includes a bot, which includes a software application for performing one or more tasks over the internet, identify that the message address corresponds to the bot, and send the message to the bot.

This overview is provided to introduce a selection of concepts in a simplified form that are further described below in the Technical Disclosure. It may be understood that this overview is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

DETAILED DESCRIPTION

The following figures and description describe various embodiments that may be used to provide bot messaging in group user node environments. Many arrangements of messaging systems 100, 200, 400, 600, 700, 900, and 1000 are possible, and the illustrated arrangements should be viewed as only exemplary arrangements of many such possible organizations.

FIG. 1 illustrates a group messaging system 100 in accordance with embodiments of the present disclosure. Group messaging system 100 includes at least user nodes 108 and a group messaging service 104. The group messaging service 104 includes one or more computers or servers that facilitate communication between user nodes 108. Each user node 108 includes at least a mobile device 112, including smart phones, PDAs, or certain wearable computers. In some embodiments, user nodes 108 include a wearable pendant 116 for wireless bidirectional audio communication with the mobile device 112. In other embodiments, user nodes 108 do not include a wearable pendant 116. In one embodiment, the wireless bidirectional communication protocol uses Bluetooth LE. Mobile device 112 may also include one or more embedded or downloadable software applications that facilitate audio communication between the wearable pendant 116 and other user nodes 108 or the group messaging service 104.

User nodes 108 may be organized into one or more groups 120, where each group 120 includes at least one user node 108. In the exemplary embodiment illustrated in FIG. 1 , two groups 120 are present in the group messaging system 100, identified as group 1 120A and group 2 120B. Group 1 120A includes three user nodes 108, identified as user node A 108A, user node B 108B, and user node C 108C. Each of the three user nodes 108 in group 1 120A includes a wearable pendant 116. Group 2 120B also includes three user nodes 108, identified as user node A 108A, user node D 108D, and user node E 108E. User node A 108A and user node D 108D each include a wearable pendant 116, while user node E 108E does not include a wearable pendant 116. In the absence of a wearable pendant 116, the user for user node E 108E communicates with the mobile device 112E as they would with any smart phone or similar mobile device 112.

Notably, both group 1 120A and group 2 120B include user node A 108A. A given user node 108 may be in none, one, or any number of groups 120. Multiple groups 120 may include different user nodes 108, or exactly the same user nodes 108. There is no limit to the association between user nodes 108 and groups 120.

When a user node 108 of a group 120 communicates with another group 120 through the group messaging service 104, messages 124 are sent wirelessly and through the internet between the communicating user nodes 108 and the group messaging service 104. Messages 124 include recorded audio (a recorded message) as well as an ID of the sending user node 108 and a group ID for the destination group the message is being delivered to. The group messaging service 104 receives the message 124, identifies the group ID associated with the message 124, looks up the user nodes 108 contained within the destination group 120, and transmits the message 124 including the ID of the sending user node 108 to each of the user nodes 108 in the destination group 120. For example, if the user of user node B 108B wanted to send a message 124 to group 2 120B, the user of user node B 108B would speak into the wearable pendant 116 and identify group 2 120B as the destination for the message 124 while speaking the audio for the message into the wearable pendant 116. An application on mobile device 112B would then create a message 124 including recorded audio as described above and send the message 124 to the group messaging service 104. The software application on the mobile device 112B would have been previously configured with the group messaging service 104. The group messaging service 104 would then receive, analyze, and transmit the message 124 to each of the user nodes in group 2 120B as described earlier. Finally, each of the users of user node A 108A, user node D 108D, and user node E 108E would receive and hear the audio for the message 124 sent by the user of user node B 108B. Use of groups 120 as described herein does not preclude sending messages 124 directly from one user node 108 to a different user node 108.

FIG. 2 illustrates a messaging flow for configuring a bot 208 into a group 120 in accordance with embodiments of the present disclosure. System 200 includes one or more groups 120 as described with reference to FIG. 1 , a group messaging service 104, and one or more existing bots 204. Bots 208 are software applications for performing one or more tasks over the internet. Therefore, bots 208 are internet-connected and in most embodiments are separate from the group messaging service 104.

Bots 208 may be incorporated into groups 120 by configuring each bot 208 in the group messaging service 104 in a similar fashion to user nodes 108. Group messaging service 104 includes data structures 212 for specifying which user nodes 108 and bots 208 are in each group 120. Each such data structure 212 includes identifiers and addresses for each user node 108 and bot 208 entity in the data structure 212. Group messaging service 104 in group messaging system 200 includes two group data structures 212, identified as group 1 data structure 212A and group 2 data structure 212B. Data structure 212A includes identifiers and addresses for each of the user nodes 108 in group 1 120. Using the example shown in FIG. 1 , data structure 212A includes a user node A 108A address and identifier, a user node B 108B address and identifier, and a user node C 108C address and identifier. Data structure 212B includes a user node A 108A address and identifier, a user node D 108D address and identifier, and a user node E 108E address and identifier. Group messaging service 104 may include any number of data structures 212, and a given bot 208 may be included in any number of data structures 212. Data structures 212 may include service IDs or identifiers for any user nodes 108, as well. Service IDs may be anything, including a user name, and email address, or anything else that uniquely identifies a user or user node 108.

A user of a user node 108 initiates adding a bot 208 to a group 120. In the example illustrated in FIG. 2 , a user in group 1 120A sends a configuration message 220 to the group messaging service 104 through the application on a corresponding mobile device 112 requesting a specific bot 208C the user has identified be added to group 1 120A. The user may not have the address of the requested bot 208C, but is at least able to uniquely identify the requested bot 208C. It is assumed that multiple existing bots 204 may be available to be messaged, and in the example of FIG. 2 , bots 208A, 208B, and 208C are available.

In response to the group messaging service 104 receiving the message 220 for bot 208C in group 1 120A, a system administrator associated with the group messaging service configures 224 data structure 212A to route messages to or from bot 208C. A bot 208C address and identifier is added to data structure 212A for group 1. In some embodiments, the system administrator may need to obtain information associated with bot 208C in order to configure data structure 212A. Typically, once the system administrator has completed configuring bot 208C into the group 1 data structure 212A, the system administrator sends a configuration message (not shown) to the group 1 120A user that sent the request 220 to add bot 208C to group 1 120. At this point, bot 208C is configured into group 1 120A along with user nodes 108A, 108B, and 108C and ready to receive messages from any user node 108 in group 1 120A. Group messaging service 104 also includes a process 216 for sending messages to a bot 208 configured in a group 120.

FIG. 3 illustrates a flowchart of a bot messaging process 216 in accordance with embodiments of the present disclosure. The bot messaging process 216 allows a user node 108 to send a message 124 to a bot 208 in a group 120. Once a bot 208 is configured into a group 120, a user node 108 may send and receive messages to and from the bot 208 through the group messaging service 104. Flow begins at block 304.

At block 304, the group messaging service 104 receives a message 124 from a user node 108 in a group 120. The message 124 includes recorded audio, a destination group 120 identifier, a bot identifier (if the message 124 is intended to be sent to a bot 208), and an identifier of the user node 108 sending the message 124. Flow proceeds to decision block 308.

At block 308, the group messaging service 104 determines if there is a bot 208 configured in the group 120 corresponding to the destination group identifier. If there is a bot 208 configured in the group 120 corresponding to the destination group identifier, then flow proceeds to decision block 316. If there is not a bot 208 configured in the group 120 corresponding to the destination group identifier, then flow instead proceeds to block 312.

At block 312, the group messaging service 104 has determined that a bot 208 is not configured in the group 120 corresponding to the destination group identifier, and therefore sends the received message 124 to the user nodes 108 within the destination group 120. Addresses for the user nodes 108 within the destination group 120 are determined by reviewing the data structure 212 within the group messaging service 104 corresponding to the destination group 120. Flow ends at block 312, or the group messaging service 104 returns to block 304 to wait for a next received message 124.

At decision block 316, the group messaging service 104 determines if the received message 124 should be sent to a specific bot 208. The group messaging service 104 reviews the data structure 212 corresponding to the destination group 120, and identifies a bot entry 504 corresponding to the bot identifier in the received message 124. A data structure 212 may include any number of bot entries 504. If there is a match, and a bot entry 504 in the data structure 212 matches the bot identifier, then flow proceeds to block 320. If there is not a match, and no bot entries 504 in the data structure 212 matches the bot identifier, then flow instead proceeds to block 312.

At block 320, the group messaging service 104 has identified a match between the received message 124 and the data structure 212 corresponding to the destination group 120, and sends the message 124 to the selected bot 208. At this point, the message 124 has been delivered to the addressed bot 208, and the addressed bot 208 carries out one or more functions corresponding to recorded audio within the message 124. In some embodiments, the bot 208 provides a data or audio acknowledgment back to the group messaging service 104, and in turn the group messaging service 104 provides the data or audio acknowledgment back to the user node 108 that sent the original message 124 or the group 120 that includes the user node 108 that sent the original message 124. In some embodiments, after the group messaging service 104 sends the message 124 to the selected bot 208, flow proceeds to block 312 and the group messaging service 104 sends the message 124 to other users and user nodes 108 within the same group 120 as the user node 108 that sent the original message 124.

FIG. 4 illustrates a messaging flow 400 for a user node 108 in accordance with embodiments of the present disclosure. The present invention allows users and user nodes 108 to send messages 124 through a group messaging service 104 to one or more bots 208, and have the one or more bots 208 perform various tasks related to the functionality of the one or more bots 208.

In some cases, bots 208 may provide enhanced functionality beyond providing information back to a requesting user node 108. For example, a bot 208 may be associated with one or more commercial services 404 that may allow purchase, sale, or other financial or more complex transactions. Bot 208 may parse message inputs to determine service handles corresponding to specific commercial services 404. In some embodiments, commercial services 404 may be associated with different user accounts, for example an account associated with a specific user or user node 108 and another account associated with a group 120. In order to utilize such commercial services 404, it is generally necessary to configure the commercial service 404 with various information 408 related to the user and user node 108 sourcing the transaction. In some embodiments, the commercial service 404 is configured at least with a user ID and a user address or IP address corresponding to a user and user node 108 who intends to use the commercial service 404. In other embodiments, the commercial service 404 is further configured with other information 408 such as, but not limited to, credit card numbers, credit card expiration dates, passwords, authentication keys, or any other information.

In the exemplary embodiment illustrated in group messaging system 400, user node C 108C sends a message 124 specifying bot 208C to the group messaging service 104. As described with reference to FIG. 3 , the group messaging service 104 identifies bot 208C is a valid recipient of the message 124, and forwards the message 124 to bot 208C. Bot 208C is associated with commercial service 404, and passes along information within the message 124 to the commercial service 404. The commercial service 404 verifies the information within the message 124 by comparing it to information 408 within the commercial service 404 that has previously been configured.

In some embodiments, commercial service 404 sends a message 412 to user node C 108C requesting service verification. For example, for improved security it may be beneficial to provide user verification for a financial transaction that may have impacts to financial accounts associated with the user of user node C 108C. In most embodiments, an application on mobile device 112C receives and displays the service verification 412 to the user, and the user verifies the transaction through the application. The application then replies to the service verification 412 and sends a reply back to the commercial service 404, where the requested transaction is then executed and acknowledged. In one embodiment, the service verification 412 and reply are sent through a different messaging channel than messages 124 that go through the group messaging service 104. In other embodiments, the service verification 412 and reply are sent through the same messaging channel than messages 124 that go through the group messaging service 104.

FIG. 5A illustrates a shared bot entry 504A within a data structure 212A in accordance with embodiments of the present disclosure. Data structures 212 may be configured one of two ways, depending on desired bot 208 performance within a group 120. In a first embodiment, data structure 212A includes a bot entry 504A that designates bot 208C as a shared bot 208. Shared bot entry 504A includes a bot address 508A and a bot identifier or ID 512A. A shared bot 208 is identified by a group 120 designation within the bot entry 504A. When a group 120 designation appears within a bot entry 504A, the group messaging service 104 treats the corresponding bot 208 (bot 208C) as a shared bot within the corresponding group 120 (group 1, as shown).

FIG. 5B illustrates a per-user bot 208 within a data structure 212A in accordance with embodiments of the present disclosure. Data structures 212 may be configured one of two ways, depending on desired bot 208 performance within a group 120. In a second embodiment, data structure 212A includes a per-user bot entry 504B that designates bot 208C as a per-user bot 208. Per-user bot entry 504B includes a bot address 508B and a bot identifier or ID 512B. A per-user bot 208 is identified by a user or user node 108 designation within the bot entry 504B. When a user or user node 108 designation appears within a bot entry 504B, the group messaging service 104 treats the corresponding bot 208 (bot 208C) as a dedicated bot 208 to a corresponding user or user node 108 (user C, as shown).

FIG. 6 illustrates messaging using a shared bot 208 with a commercial service 404 in accordance with embodiments of the present disclosure. The present invention allows users and user nodes 108 to send messages 124 through the group messaging service 104 to one or more shared bots 208, and have the one or more shared bots 208 perform various tasks related to the functionality of the one or more shared bots 208. As described with reference to FIG. 5A, shared bots 208 are bots 208 assigned to a specific group 120 instead of a specific user or user node 108. Any user node 108 within a group 120 may send a message to a shared bot 208 configured within the same corresponding group's data structure 212A, and the group messaging service 104 will respond accordingly. Otherwise, the group messaging service 104 will send a notification to the requesting user or user node 108 that the shared bot 208 is currently not assigned to the group 120 of the requesting user or user node 108.

Data structure 212A includes one or more shared bot entries 504A. Data structure 212A may also contain both shared bot entries 504A and per-user bot entries 504B. Each shared bot entry 504A includes a bot address 508A and a bot identifier or ID 512A. Group messaging service 104 includes a process 604, shown in more detail in FIG. 8 , that selects a specific shared bot entry 504A corresponding to the message 124, and sends a message specifying the group ID 612 to the selected shared bot 208. It should be understood that the shared bot 208, and the commercial service 404 if applicable, provides a response to the group messaging service 104 at least related to completion of the requested task in the message 612. The group messaging service 104 would then provide a notification to each of the user nodes 108 in the requesting group 120A.

In some cases, shared bots 208 may provide enhanced functionality beyond providing information back to a requesting user node 108. For example, a shared bot 208 may be associated with one or more commercial services 404 that may allow purchase, sale, or other financial or more complex transactions. In order to utilize such commercial services 404, it is generally necessary to configure the commercial service 404 with various information 608 related to the group 120 and user node 108 sourcing the transaction. In the case of a shared bot 208, the commercial service 404 is configured at least with an account ID, an ID corresponding to the group 120, and an IP address corresponding to the group 120 for the user nodes 108 whose users intend to use the commercial service 404. In other embodiments, the commercial service 404 is further configured with other information 608 such as, but not limited to, credit card numbers, credit card expiration dates, passwords, authentication keys, or any other information.

In the exemplary embodiment illustrated in group messaging system 600, a user node 108 in group 1 120A sends a message 124 specifying shared bot 208 to the group messaging service 104. As described with reference to FIG. 6 , the group messaging service 104 identifies shared bot 208 is a valid recipient of the message 124, and forwards the message 124 to shared bot 208. Shared bot 208 is associated with commercial service 404, and passes along information within the message 124 to the commercial service 404. The commercial service 404 verifies the information within the message 124 by comparing it to information 608 within the commercial service 404 that has previously been configured for the group 120.

In one embodiment, the group messaging service 104 and data structure 212A may be configured to forward all messages 124 from group 1 120A to a specific bot 208, without the specific bot 208 being explicitly addressed. In this way, a specific bot 208 may be effectively monitoring all conversations within group 1 120A between user nodes 108 of group 1 120A, and acting upon predetermined identified audio within each recorded message 124.

In some embodiments (not shown), commercial service 404 sends a message to one or more user nodes 108 of the corresponding group 120 requesting service verification. For example, for improved security it may be beneficial to provide user verification for a financial transaction that may have impacts to financial accounts associated with the group 120. In most embodiments, an application on mobile devices 112 in the group 120 receives and displays the service verification to the user(s), and the user(s) verify the transaction through a mobile device 112 application. The application then replies to the service verification and sends a reply back to the commercial service 404, where the requested transaction is then executed and acknowledged. In one embodiment, the service verification and reply are sent through a different messaging channel than messages 124 that go through the group messaging service 104. In other embodiments, the service verification and reply are sent through the same messaging channel than messages 124 that go through the group messaging service 104.

FIG. 7 illustrates messaging using a per-user bot 208 with a commercial service 404 in accordance with embodiments of the present disclosure. The present invention allows users and user nodes 108 to send messages 124 through the group messaging service 104 to one or more per-user bots 208, and have the one or more per-user bots 208 perform various tasks related to the functionality of the one or more per-user bots 208. As described with reference to FIG. 5B, per-user bots 208 are bots 208 assigned to a specific user or user node 108 instead of a group 120. Any user node 108 within a group 120 may send a message 124 to a per-user bot 208 configured within the corresponding group's data structure 212A, and the group messaging service 104 will process the message to the per-user bot 208 if the per-user bot 208 is configured to the sending user or user node 108C. Otherwise, the group messaging service 104 will send a notification to the requesting user or user node 108 that the per user bot 208 is currently not assigned to the requesting user or user node 108.

Data structure 212A includes one or more per-user bot entries 504. Data structure 212A may also contain both shared bot entries 504A and per-user bot entries 504B. Each per-user bot entry 504B includes a bot address 508B and a bot identifier or ID 512B. Group messaging service 104 includes a process 604, shown in more detail in FIG. 8 , that selects a specific per-user bot entry 504A corresponding to the message 124, and sends a message specifying the user ID 708 to the selected per-user bot 208. It should be understood that the per-user bot 208, and the commercial service 404 if applicable, provides a response to the group messaging service 104 at least related to completion of the requested task in the message 708. The group messaging service 104 would then provide a notification to the user node 108C that sent the original message 124.

In some cases, per-user bots 208 may provide enhanced functionality beyond providing information back to a requesting user node 108C. For example, a per-user bot 208 may be associated with one or more commercial services 404 that may allow purchase, sale, or other financial or more complex transactions. In order to utilize such commercial services 404, it is generally necessary to configure the commercial service 404 with various information 704 related to the user and user node 108C sourcing the transaction. In the case of a per-user bot 208, the commercial service 404 is configured at least with an account ID, an ID corresponding to the user or user node 108C, and an IP address corresponding to the user node 108C whose user intends to use the commercial service 404. In other embodiments, the commercial service 404 is further configured with other information 704 such as, but not limited to, credit card numbers, credit card expiration dates, passwords, authentication keys, or any other information.

In the exemplary embodiment illustrated in group messaging system 700, user node 108C sends a message 124 specifying per-user bot 208 to the group messaging service 104. As described with reference to FIG. 8 , the group messaging service 104 identifies per-user bot 208 is a valid recipient of the message 124, and forwards the message 124 to per-user bot 208. Per-user bot 208 is associated with commercial service 404, and passes along information within the message 124 to the commercial service 404. The commercial service 404 verifies the information within the message 124 by comparing it to information 704 within the commercial service 404 that has previously been configured for the user and user node 108C.

In one embodiment, the group messaging service 104 and data structure 212A may be configured to forward all messages 124 from a specific user node C 108C to a specific bot 208, without the specific bot 208 being explicitly addressed. In this way, a specific bot 208 may be effectively monitoring all conversations from user node C 108C between user nodes 108 of group 1 120A, and acting upon identified audio within each recorded message 124 from user node C 108C.

In some embodiments (not shown), commercial service 404 sends a message to user node 108C requesting service verification. For example, for improved security it may be beneficial to provide user verification for a financial transaction that may have impacts to financial accounts associated with the user of user node 108C. In most embodiments, an application on mobile device 112 of user node 108C receives and displays the service verification to the user, and the user verifies the transaction through the mobile device 112 application. The application then replies to the service verification and sends a reply back to the commercial service 404, where the requested transaction is then executed and acknowledged. In one embodiment, the service verification and reply are sent through a different messaging channel than messages 124 that go through the group messaging service 104. In other embodiments, the service verification and reply are sent through the same messaging channel than messages 124 that go through the group messaging service 104.

FIG. 8 illustrates a flowchart of a messaging process 604 using shared or per-user bots 208 in accordance with embodiments of the present disclosure. The bot messaging process 604 allows a user node 108 to send a message 124 to either a shared bot 208 or a per-user bot 208 in a group 120. Once a bot 208 is configured into a group 120, a user node 108 may send and receive messages 124 to and from the bot 208 through the group messaging service 104. Flow begins at block 804.

At block 804, the group messaging service 104 receives a message 124 from a user node 108 in a group 120. The message 124 includes recorded audio, a destination group 120 identifier, a bot identifier (if the message 124 is intended to be sent to a bot 208), and an identifier of the user node 108 sending the message 124. Flow proceeds to decision block 808.

At block 808, the group messaging service 104 determines if there is a bot 208 configured in the group corresponding to the destination group 120 identifier. If there is a bot 208 configured in the group 120 corresponding to the destination group 120 identifier, then flow proceeds to decision block 812. If there is not a bot 208 configured in the group 120 corresponding to the destination group 120 identifier, then flow instead proceeds to block 832.

At decision block 812, the group messaging service 104 determines if the received message 124 should be sent to a specific shared bot 208. The group messaging service 104 reviews the data structure 212 corresponding to the destination group 120, and identifies a shared bot entry 504A corresponding to the bot identifier in the received message 124. A data structure 212 may include any number of shared or per-user bot entries 504A/504B. If there is a match, and a shared bot entry 504A in the data structure 212 matches the bot identifier, then flow proceeds to decision block 816. If there is not a match, and no shared bot entries 504A in the data structure 212 match the bot identifier, then the received message should be sent to a per-user bot 208 and flow instead proceeds to decision block 824.

At decision block 816, the group messaging service 104 determines if the message 124 qualifies. A qualified message 124 is a message with content that conforms with a bot entry 504A/504B in the data structure 212. With respect to decision block 816, since there is a bot 208 involved (decision block 808) and the bot 208 is a shared bot 208 (decision block 812), the message 124 must be sent by a user node 108 in the same data structure 212 as the shared bot 208. Therefore, a qualified user node 108 has transmitted the message 124 and is able to have the message 124 sent to the shared bot 208. If the message qualifies, then flow proceeds to block 820. If the message does not qualify, then flow instead proceeds to block 832.

At block 820, the group messaging service 104 has identified a match between the received message 124 and the data structure 212 corresponding to the destination group 120, and sends the message 124 to the selected shared bot 208. At this point, the message 124 has been delivered to the addressed shared bot 208, and the addressed shared bot 208 carries out one or more functions corresponding to recorded audio within the message 124. In some embodiments, the shared bot 208 provides a data or audio acknowledgment back to the group messaging service 104, and in turn the group messaging service 104 provides the data or audio acknowledgment back to the user node 108 that sent the original message 124 or the group 120 that includes the user node 108 that sent the original message 124. In some embodiments, after the group messaging service 104 sends the message 124 to the selected shared bot 208, flow proceeds to block 832 and the group messaging service 104 sends the message 124 to other users and user nodes 108 within the same group 120 as the user node 108 that sent the original message 124.

At decision block 824, the group messaging service 104 determines if the message 124 qualifies. A qualified message 124 is a message with content that conforms with a bot entry 504A/504B in the data structure 212. With respect to decision block 824, since there is a bot 208 involved (decision block 808) and the bot 208 is a per-user bot 208 (decision block 812), the message 124 must be sent by a user node 108 in the same data structure 212 as the per-user bot 208. Therefore, a qualified user node 108 has transmitted the message 124 and is able to have the message 124 sent to the per-user bot 208. If the message qualifies, then flow proceeds to block 828. If the message does not qualify, then flow instead proceeds to block 832.

At block 820, the group messaging service 104 has identified a match between the received message 124 and the data structure 212 corresponding to the destination group 120, and sends the message 124 to the selected per-user bot 208. At this point, the message 124 has been delivered to the addressed per-user bot 208, and the addressed per-user bot 208 carries out one or more functions corresponding to recorded audio within the message 124. The per-user bot 208 provides a data or audio acknowledgment back to the group messaging service 104, and in turn the group messaging service 104 provides the data or audio acknowledgment back to the user node 108 that sent the original message 124. In some embodiments, after the group messaging service 104 sends the message 124 to the selected per-user bot 208, flow proceeds to block 832 and the group messaging service 104 sends the message 124 to other users and user nodes 108 within the same group 120 as the user node 108 that sent the original message 124.

At block 832, the group messaging service 104 has determined that a bot 208 is not configured in the group corresponding to the destination group 120 identifier (decision block 808) or the message 124 is not qualified (decision block's 816 and 824), and therefore sends the received message 124 to the user nodes 108 within the destination group 120. Addresses for the user nodes 108 within the destination group 120 are determined by reviewing the data structure 212 within the group messaging service 104 corresponding to the destination group 120. Flow ends at block 832, or the group messaging service 104 returns to block 804 to wait for a next received message 124.

FIG. 9 illustrates a bot system 900 architecture in accordance with a first embodiment of the present disclosure. Once a group messaging service 104 has been configured to use one or more bots 208, user nodes 108 within groups 120 may send and receive messages from the bots 208. In some embodiments, bots 208 may be configured to respond to enhanced text 916, rather than recorded messages 124 as described previously. In such cases, group messaging service 104 must be able to convert audio from the recorded messages 124 into enhanced text 916 which may be sent to a bot 208 to execute one or more actions.

A group, such as group 1 120A includes one or more user nodes 108, including user node B 108B including mobile device 112B and wearable pendant 116. User node 108B sends a recorded message with encoded audio 904 to the group messaging service 104, where the recorded message 904 is directed to a bot 208 in group 1 120A. Group messaging service 104 decodes the encoded audio in the recorded message 904 to create decoded audio 908. Group messaging service 104 executes process 940 to identify a bot 208 and voice library, and direct the recorded message to users and bots 208 appropriately. Process 940 is shown and described in more detail with respect to FIG. 11 .

Group messaging service 104 either includes a voice library as part of group messaging service 104, or has access to one or more remote voice libraries. Voice libraries include at least a speech-to-text engine 902 and a natural language unit 903. In some embodiments, the speech-to-text engine 902 is part of group messaging service 104 while the natural language unit 903 is remote. In other embodiments, the speech-to-text engine 902 is remote while the natural language unit 903 is part of group messaging service 104. Remote portions of the voice library are accessed through Gateway processing 901. Data structures 212 of the group messaging service 104 need to be configured as to whether voice libraries are required to be used for group messages, or not. For example, some bots 208 may require a voice library to be used while other bots 208 may not.

The group messaging service 104 sends the decoded audio to the speech-to-text engine 902, and the speech-to-text engine 902 converts the decoded audio into text 912 and sends the text 912 to the group messaging service 104. In some embodiments, the speech-to-text engine 902 sends the text 912 directly to the natural language unit 903. After receiving the text 912, the group messaging service 104 sends the text 912 to the natural language unit 903, which reviews the text 912 and converts the text 912 into enhanced text 916. Enhanced text 916 is clarified and simplified from text 912 into a form more suitable for presentation to a bot 208 to execute. The natural language unit 903 sends the enhanced text 916 to the group messaging service 104.

After receiving the enhanced text 916 from the natural language unit 903, the group messaging service 104 sends the enhanced text 916 to the selected bot 208 corresponding to the recorded message 904. Bot 208 receives the enhanced text 916 and in response, performs one or more designated actions 920 corresponding to the decoded audio 908 and enhanced text 916. In some embodiments, bot 208 is associated with one or more commercial services 404, such as order management systems or systems involving various financial transactions. Bot 208 forwards an order 936 or other commercial service request to commercial service 404 for execution. As previously described, commercial service 404 would need to be previously configured by the user of user node B 108B with payment, account number, IP address, or any other required information. Commercial service 404, after verifying the transaction with mobile device 112B, then carries out the requested order 936. Bot 208 would then send a reply 924 to the group messaging service 104 with various information including at least completion of the request corresponding to the enhanced text 916.

In response to receiving the reply 924 from the bot 208, the group messaging service 104 forwards a reply 928 to group 1 120A including user node B 108B. Optionally, group messaging service 104 provides the original recorded message to the group 932 in order to inform other user nodes 108 of group 1 120A of the request made by user node B 108B. At this point, all actions with recorded message 904 have been carried out and the requested transaction has been completed.

FIG. 10 illustrates a bot system 1000 architecture in accordance with a second embodiment of the present disclosure. FIG. 10 illustrates a more complex embodiment to that illustrated bot system 900 of FIG. 9 . Bot system 1000 includes alternative voice libraries directly accessible by bot 208.

A group, such as group 1 120A includes one or more user nodes 108, including user node B 108B including mobile device 112B and wearable pendant 116. User node 108B sends a recorded message with encoded audio in a PCU format 1016 to the group messaging service 104, where the recorded message 904 is directed to a bot 208 in group 1 120A. Group messaging service 104 decodes the encoded audio in the recorded message 904 to create decoded audio 908. Group messaging service 104 executes process 940 to identify a bot 208 and voice library, and direct the recorded message to users and bots 208 appropriately. Process 940 is shown and described in more detail with respect to FIG. 11 .

For embodiments where the group messaging service 104 interfaces with and controls voice libraries, group messaging service 104 either includes a voice library as part of group messaging service 104, or has access to one or more remote voice libraries 1004. Voice libraries 1004 include at least Gateway processing 901, a speech-to-text engine 902A and a natural language unit 903A. Voice libraries 1004 may be accessible through one or more application programming interfaces (APIs). In some embodiments, the speech-to-text engine 902A is part of group messaging service 104 while the natural language unit 903A is remote. In other embodiments, the speech-to-text engine 902A is remote while the natural language unit 903A is part of group messaging service 104. In some embodiments, a generic speech-to-text engine 902A may be used in conjunction with multiple natural language units 903. For example, one natural language unit 903 may be used for restaurant or food-related messages, another natural language unit 903 may be used for document or publication-related messages, and another natural language unit 903 may be used for scheduling related messages.

Data structures 212 of the group messaging service 104 need to be configured as to whether voice libraries are required to be used for group messages, or not. Also, if multiple voice libraries 1004, 1008, 1012 are available, data structures 212 may indicate which voice library is used for each bot 208. For example, some bots 208 may require a voice library to be used while other bots 208 may not.

The group messaging service 104 sends the decoded audio 1020 to the speech-to-text engine 902A, and the speech-to-text engine 902A converts the decoded audio into text and sends the text directly to the natural language unit 903A. The natural language unit 903A reviews the text and converts the text into enhanced text 1024, and sends the enhanced text 1024 to the group messaging service 104. Enhanced text 1024 is clarified and simplified text in a form more suitable for presentation to a bot 208 to execute.

After receiving the enhanced text 1024 from the natural language unit 903A, the group messaging service 104 sends the enhanced text 1028 to the selected bot 208 corresponding to the recorded message 1016. Bot 208 receives the enhanced text 1028 and in response, performs one or more designated actions 1040 corresponding to the decoded audio 1020 and enhanced text 1028. In some embodiments, bot 208 is associated with one or more commercial services 404, such as order management systems or systems involving various financial transactions. Bot 208 forwards one or more orders 1044 or other commercial service request to one or more commercial services 404 for execution. As previously described, commercial services 404 would need to be previously configured by the user of user node B 108B with payment, account number, IP address, or any other required information. Commercial services 404, after verifying the transaction with mobile device 112B, then carries out the requested order 1044. Bot 208 would then send a text reply 1028 to the group messaging service 104 with various information including at least completion of the request corresponding to the enhanced text 1028.

In response to receiving the text reply 1028 from the bot 208, the group messaging service 104 forwards a reply 1052 to group 1 120A including user node B 108B. Optionally, group messaging service 104 provides the original recorded message to the group 1056 in order to inform other user nodes 108 of group 1 120A of the request made by user node B 108B. At this point, all actions with recorded message 1016 have been carried out and the requested transaction has been completed.

A second embodiment where the bot 208 directly interfaces with voice libraries 1012 is now described. After the group messaging service 104 receives the recorded message with encoded audio (.PCU format) 1016, the group messaging service 104 forwards the .PCU audio 1032 to a .PCU to .WAV voice library 1008. The .PCU to .WAV voice library 1008 converts the audio in .PCU format 1032 to .WAV format 1036. The .PCU to .WAV voice library 1008 is also able to convert audio in .WAV format 1036 to .PCU format 1032. The .PCU to .WAV voice library 1008 may either be part of group messaging service 104 or remote from group messaging service 104. The .PCU to .WAV voice library 1008 sends the .WAV audio 1036 to the bot 208.

Bot 208 has an associated bot voice library 1012, including a speech-to-text engine 902B and a natural language unit 903B. Bot voice library 1012 converts .WAV audio 1036 into enhanced text. The enhanced text may be required by the bot 208 in order to perform designated actions 1040, or may be required by one or more commercial services 404 to perform additional actions including processing orders or financial transactions. In one embodiment, bot 208 performs designated actions 1040 after receiving the .WAV audio 1036 but before converting the .WAV audio 1036 into enhanced text with bot voice library 1012. In another embodiment, bot 208 performs designated actions 1040 after receiving the .WAV audio 1036 and after converting the .WAV audio 1036 into enhanced text with bot voice library 1012.

After bot 208 has completed all designated actions 1040, bot 208 sends an audio reply 1048, usually in compressed .MP3 format, to the .PCU to .WAV voice library 1008. The .PCU to .WAV voice library 1008 converts audio in .MP3 format 1048 into .PCU audio 1032, and sends the .PCU audio 1032 to the group messaging service 104. The group messaging service 104 receives the .PCU audio 1032 and a reply, and sends a reply 1052 to group 1 120A, including user node B 108B. Optionally, the group messaging service 104 sends the original message to the group 1056. At this point, all actions with recorded message 1016 have been carried out and the requested transaction has been completed.

FIG. 11 illustrates a flowchart of a bot architecture message flow process 940 using voice libraries in accordance with embodiments of the present disclosure. The bot messaging process 940 allows a user node 108 of a group 120 to send a message 124 to various configurations of bots 208 and voice libraries. Once a bot 208 is configured into a group 120, a user node 108 may send and receive messages to and from the bot 208 through the group messaging service 104. Flow begins at block 1104.

At block 1104, the group messaging service 104 receives a message 124 from a user node 108 in a group 120. The message 124 includes recorded audio, a destination group 120 identifier, a bot identifier (if the message 124 is intended to be sent to a bot 208), and an identifier of the user node 108 sending the message 124. Flow proceeds to decision block 1108.

At block 1108, the group messaging service 104 determines if there is a bot 208 configured in the group 120 corresponding to the destination group 120 identifier. If there is a bot 208 configured in the group 120 corresponding to the destination group 120 identifier, then flow proceeds to block 1116. If there is not a bot 208 configured in the group 120 corresponding to the destination group 120 identifier, then flow instead proceeds to block 1112.

At block 1112, the group messaging service 104 has determined that a bot 208 is not addressed in the message 124 (decision block 1108) or the message 124 is not qualified (decision blocks 1124 and 1132), and therefore sends the received message 124 to the user nodes 108 within the destination group 120. Addresses for the user nodes 108 within the destination group 120 are determined by reviewing the data structure 212 within the group messaging service 104 corresponding to the destination group 120. Flow ends at block 1112, or the group messaging service 104 returns to block 1104 to wait for a next received message 124.

At block 1116, the group messaging service 104 selects a voice library 1004, 1008, 1012 to apply to the message 124. If only a single voice library is available, the group messaging service 104 selects that voice library. In some embodiments, voice libraries 1012 may be specific to a bot 208. In other embodiments, voice libraries 1004 may be general-purpose and able to be used with many such bots 208. In yet other embodiments, voice libraries 1008 may be used to convert recorded audio from one format to another format. Flow proceeds to decision block 1120.

At decision block 1120, the group messaging service 104 determines if the received message 124 should be sent to a specific shared bot 208. The group messaging service 104 reviews the data structure 212 corresponding to the destination group 120, and attempts to identify a shared bot entry 504A corresponding to the bot identifier in the received message 124. A data structure 212 may include any number of shared or per-user bot entries 504A/504B. If there is a match, and a shared bot entry 504A in the data structure 212 matches the bot identifier, then flow proceeds to decision block 1124. If there is not a match, and no shared bot entries 504A in the data structure 212 match the bot identifier, then the received message should be sent to a per-user bot 208 and flow instead proceeds to decision block 1132.

At decision block 1124, the group messaging service 104 determines if the message 124 qualifies. A qualified message 124 is a message with content that conforms with a bot entry 504A/504B in the data structure 212. With respect to decision block 1124, since there is a bot 208 involved (decision block 1108) and the bot 208 is a shared bot 208 (decision block 1120), the message 124 must be sent by a user node 108 in the same data structure 212 as the shared bot 208. Therefore, a qualified user node 108 has transmitted the message 124 and is able to have the message 124 sent to the shared bot 208. If the message qualifies, then flow proceeds to block 1128. If the message does not qualify, then flow instead proceeds to block 1112.

At block 1128, the group messaging service 104 has identified a match between the received message 124 and the data structure 212 corresponding to the destination group 120, and sends the message 124 to the selected shared bot 208. At this point, the message 124 has been delivered to the addressed shared bot 208, and the addressed shared bot 208 carries out one or more functions corresponding to recorded audio within the message 124. In some embodiments, the shared bot 208 provides a data or audio acknowledgment back to the group messaging service 104, and in turn the group messaging service 104 provides the data or audio acknowledgment back to the user node 108 that sent the original message 124 or the group 120 that includes the user node 108 that sent the original message 124. In some embodiments, after the group messaging service 104 sends the message 124 to the selected shared bot 208, flow proceeds to block 1112 and the group messaging service 104 sends the message 124 to other users and user nodes 108 within the same group 120 as the user node 108 that sent the original message 124.

At decision block 1132, the group messaging service 104 determines if the message 124 qualifies. A qualified message 124 is a message with content that conforms with a bot entry 504A/504B in the data structure 212. With respect to decision block 1132, since there is a bot 208 involved (decision block 1108) and the bot 208 is a per-user bot 208 (decision block 1120), the message 124 must be sent by a user node 108 in the same data structure 212 as the per-user bot 208. Therefore, a qualified user node 108 has transmitted the message 124 and is able to have the message 124 sent to the per-user bot 208. If the message qualifies, then flow proceeds to block 1136. If the message does not qualify, then flow instead proceeds to block 1112.

At block 1136, the group messaging service 104 has identified a match between the received message 124 and the data structure 212 corresponding to the destination group 120, and sends the message 124 to the selected per-user bot 208. At this point, the message 124 has been delivered to the addressed per-user bot 208, and the addressed per-user bot 208 carries out one or more functions corresponding to recorded audio within the message 124. The per-user bot 208 provides a data or audio acknowledgment back to the group messaging service 104, and in turn the group messaging service 104 provides the data or audio acknowledgment back to the user node 108 that sent the original message 124. In some embodiments, after the group messaging service 104 sends the message 124 to the selected per-user bot 208, flow proceeds to block 1112 and the group messaging service 104 sends the message 124 to other users and user nodes 108 within the same group 120 as the user node 108 that sent the original message 124.
